One day, a UFO landed in front of me when I was walking down the street. An alien got out. I was very afraid, and followed it. The alien went into a souvenir shop. While it was looking at the souvenirs, the shop assistant called the police. Before the police arrived, the alien left the shop and went into a museum. When the alien was in the museum, I called the TV station. That was amazing!
